To all 'whom it may concern:

Be it known that I, DAVID RussELL GREENE, a citi-v zen of the United States of Amel-ica, and a resident o f Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Music-Rolls for Piano- 'las, of which the following is a specification.

My invention relates to music rolls for pianolas, or

. other similar piano or organ players. With rolls of this character more or less trouble has been experi- 0 enced, owing to the uneven expansion and contraction of the wood' of the roll and the paper of the music wound thereon. These rolls are usually provided with end flanges, and the perforated sheet of paper constituting the music is wound upon the roll between these flanges.

15 With such arrangement, it is some times found that the paper expands and bears so hard on the said flanges that it-does not unwind properly. Again, too much space will perhaps show its presence between the flanges and the ends ofthe roll of paper, thus interfering with the proper winding and unwinding of the music.

Generally stated, the object of my invention is the provision of an Iimproved construction for permitting the adjustment of the roll in accordance with the ex- 'pansion and contraction of the paper and wood-that is to say, the provision of improved means by which the flanges of the roll can always be adjusted in the same manner as to preserve the proper relation between these flanges and the ends of the paper` roll, thus making it possible to move the flanges either toward or away from the paper roll, as conditions may require.

Special objects of my invention are the provision of A an improved ange-adjusting arrangement, lwhereby the flanges can be adjusted readily by hand, without the use of tools and'without inserting or removing .any parts or devices; and the provision of certain details and features of improvement and combinations tending to increase the v general efficiency and ser'viceability of an'adjustable music roll of this particular character. To the foregoing and other useful ends my invention 40 consists in matters hereinafter setorth and claimed. I In the accompanying drawings-Figure l is an enlarged side elevation of a musicroll embodying the principles of my invention, the same being broken away at the middle for the convenience of illustration, 4 5 and one end being shown in longitudinal section., I'ig.. 2 is anend elevation of the said roll. Fig. 3 is a cross section on line 3-3 in Fig. v1. i i

-As thus illustrated, my improved music roll comprises the cylinder or roll of wood A, which is provided with reduced end portionsa. The 'spindles Band B1 v I are preferably of metal land are inserted in the ends of slewing@ shown, A threaded sleeve o is freed uponv feach reduced end portion a of the roll.' Upon these sleevesiare screwed the adjustable metal flanges D.

i: 'These of course,'.oir' greater diameter than the cylinder of wood A, so as to expose more or less of their inner faces. Each flange has its inner face provided with sockets d arranged on the line of the' circle.v and each socket being preferably rounded', as shown.- The roll or cylinder of wood 'A is provided with short line with the sockets d. Each tube 'contains a catch or locking device E and a spring e, the latter tending to of the adjacent flange D. I With this arrangement, the spring-.pressed pins or locking devices E engage the sockets 0? with suflicient pressure to prevent the winding and unwinding of the music F from rotating the GNQRAF @Nara-ian o 'GEORGE tubes at inserted in the ends thereof, and arranged in4 jkeep the former pressed tightly against the' inner face i flanges D.. In other words, the flanges will remain at any desired position where they may be adjusted by rotating them upon the screw-threaded sleeves C. At the same time, however, these flanges can be grasped and rotated in order to bring them to the desired positions, the tendency of the Springs e being insufficient to resist the rotation thus given the flanges. For this purpose, the ends of the pins or locking devices E are rounded, as shown. In this way, as stated, the winding and unwinding of the music will not disturb the flanges, but, at the same time,- either ,flange can be grasped and rotated for the purposeV of changing' its position relatively to the end of the roll of paper. Consequently, the flanges can always be quickly adjusted relatively to the roll of paper when the latter shrinks or contracts.4 -This, 'of course, will tend to guard against tearing of the paper, and will insure accuracy in playing after the roll is inserted-in the player. v Y

What I claim as my invention is:- 1. In a music roll of the character specified, the combination .of a cylinder, rotatable flanges for -the ends of said cylinder, spring-pressed pins for engaging said-flanges and yeldingly holding the same in any desired position,

- and perforatedmusic wound upon the cylinder between said ilanges.

2. In a music roll of the character specied, the combination otthe cylinder A, the `threadcd sleeve C secured to the ends thereof, screw-threaded flanges D screwed upon said sleeves, each flange provided with sockets -d, the spring-pressed pins E adapted to engage said sockets en cylinder between the flanges, substantially as set forth.

vthe anges, and the perforated music F Wound upon the In a mu'sicroll of the character specified, the colnbination ofp'a cylinder of wood provided with reduced end y portions, sleeves, screw-threaded flanges secured upon said sleeves, said anges being of greater diameter than said cylinder of wood; and means between the two flanges for holding either flange in any' desired position relatively to the ends of the cylinder. y

4. In a music roll of the character specified, the combination of a cylinder provided with threaded end portions,

flanges screwed upon said threaded end portions, and

-spring-pressed members adapted toengage 4the inner I aces of said flanges to hold the saine in any desired relation to the endsof the cylinder.

5. In a music roll ott-,he character specified, the combination of a cylinder provided with threaded end portions,
